METAL-DIPPING MACHINE.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed June 11, 1907. Serial No. 378,386.

To all whom it may concern:

Be it known that I, CHARLES F. NEU- REUTHER, a citizen of the United States, residing in the city of Peru, in the county of Lasalle and State of Illinois, have invented a certain new and useful Metal-Dipping Machine, of which the following is a specification.

My invention relates to improvements in the art of dipping molten metals, and has for its object the production of a machine for dipping a certain definite amount of molten metal from a tank or pot containing same, and delivering it into a mold or other receptacle.

The particular form of my invention I have here described is that which I use in dipping molten zinc, after it has been melted preparatory to the rolling of said zinc. Zinc being a heavy metal, and melting at a low red heat, makes the present method of manually handling same very undesirable and disagreeable to the men doing this work. My invention entirely eliminates all these undesirable features, encountered in doing this work.

In the drawings Figure 1 represents a front view of one form of my invention. Fig. 2 is a vertical cross sectional view through Fig. 1.

Similar numerals refer to similar parts throughout the drawings.

A horizontal base plate 1, is fastened, by any of the usual means, to a tank or pot 6 which contains the molten metal. up to the level indicated at 47. i y

Depending from base plate 1 is a tubular member 7 having the internally bored cylin drical part 2 and a series of circumferentially disposed apertures, one shown at 4 below the surface of the metal, several at 3 partly submerged, and one 45 immediately above the surface of the metal. Fastened to said aperture 45 is the delivery spout 42 under the end of which is a mold 44.

Fitted to the bored part 2 of member 7 is the dipper or ladle 8, which is reciprocated vertically, (it being in its highest position shown in the full lines in Fig. 2 and in its lowest position by the dotted lines in said Fig. 2,) by means of the rod 9 rigidly fastened in the bottom of 8. Dipper 8 has an aperture 10 near its bottom which when the dipper is in its highest position, connects with the spout 42 by means of the aperture 45.

Fastened to the base plate 1, by means of the feet 23 and the bolts 24 is the frame 14, which carries the mechanism for reciprocating the dipper 8. This mechanism comprises a cross-head 11 which slides in suitable bearings in projections 15 and 38 which form a part of frame 14, said crosshead being held in said bearings by means of the cover plates 16 and 12 respectively. Crosshead 11 has a recess 13 along its length into which the rod 9 passes, said rod 9 being fastened to crosshead 11 by means of pin 60. The function of the 'recess 13 is to permit the removing and the putting in of the various dippers as will be explained further along. Crosshead 11 has a curved slot 34, ending with the straight portions 35, in which the roll 17 operates, roll 17 being journaled on a pin 18 fastened to the crank plate 19, which in turn is fastened to a shaft 20 which is journaled in the frame 14 and a boss 21 projecting from said frame. Shaft 20 is actuated by means of a wormwheel 22 which is fastened to it, and engages the worm 27 which is fastened to a shaft 28 which is journaled in the bearings 29 mounted on a projection 30 from frame 14. Shaft 28 also has journaled on it'the driving wheel 25 which is driven by means of belt 26. Slidably mounted on said shaft 28, but rotatably fastened to it, is the clutch jaw 32 whose counterpart 31 is rigidly fastened to the pulley 25. 7 Clutch jaw 32 is thrown in and out of engagement by means of lever 33 which is fastened to the base 1 by means of rod and pin 39. The curved part of slot 34 in crosshead 11 has the same radius that the roll 17 has from the center of shaft 20 so that when roll 17 is traveling, as disk 19 rotates, this part of the slot when. same is above the center of shaft 20, the crosshead is at rest. As this occurs when the dipper is in the highest position, it gives the said dipper 8 a period of rest in which it can empty all its contents into the delivery spout 42, through the aperture as shown in Fig. 2. This permits the machine to run continuously, so that the operator needs only to bring a series of molds in line under the delivery spout to receive the metal.

It is evident that so long as the opening 10 in dipper 8 is away from the aperture 45 it cannot lose any of its contents, since the aperture 10 is closed by the wall of the bore 2.

In order to produce slabs of metal having different weights Various heights of dippers are used, the dippers being removed and inserted by removing the pin 60 and pulling up rod 9 into the recess 13 on crosshead 11 until the dipper 8 is out of 2, when the dipper can be removed, the cover plate 12 being made in two parts to allow the rod 9 to pass through it.

In operation my machine works as follows: Starting with the position shown in the drawings as the crank plate 19 is rotated, as long as roll 17 is in the curved part of slot 34 the dipper will remain stationary. As soon as the roll 17 strikes the straight part of the slot 35 the dipper will be forced down beneath the surface of the metal, when it will be filled by the molten metal coming through the slots 3 and 1,; then as disk 19 continues to rotate it will raise the dipper and gradually bring it back to the positionshown in the drawings, permitting the aperture 10 to open, gradually as it were, and thus prevent excessive splashing of the metal into the mold 44. Apertures 3 permit any metal over the dipper full to pass again into the tank as the dipper passes out of the surface of the metal.

If the delivery spout 42 is long it is neces sary, especially if the machine is operated intermittently, to employ means to keep it hot. F or this purpose ll is a chamber in connection with the tank or pot, and 43 is a stack leading from said chamber, producing a draft which draws the fire and the hot gases from the furnace used in melting the liietal, around the delivery spout keeping it ot. It will be understood, of course, that the various portions of my machine could be used with features greatly modified. In short, I do not wish to be understood as limiting myself to one particular form, arrangement, and grouping of these several features, elements or parts; but I have here presented that form of a machine which I am now using with the intention of having it taken in a sense diagrammatic or descriptive of that class of machines which could be produced any one of which would contain the substance of all or most of my invention.

I claim:

1. In a metal dipping machine, a dipper comprising a cylindrical bucket having an aperture adjacent to its bottom, said bucket being slidably mounted in a tube having a plurality of circumferentially disposed slots and an aperture communicating with a delivery spout, with means for reciprocating and giving said bucket a period of rest in its extreme upper position.

2. In a metal dipping machine, a dipper comprising a cylindrical bucket having an aperture adjacent to its bottom, said bucket being slidably mounted in a tubular member having a plurality of circumferentially disposed slots and an aperture communicating with a delivery spout, with means for reciprocating and giving said bucket a period of rest in its extreme upper position,'said means comprising a crosshead, a curved slot in said crosshead, a roll in said slot, said roll being journaled on a pin fastened to a crank plate fastened to a shaft having rotary motion.

3. In a metal dipping machine, a dipper comprising a cylindrical bucket, an aperture adjacent to the bottom of said bucket, said bucket being slidably mounted in a tube having a plurality of circumferentially disposed slots and an aperture communicating with a delivery spout, in combination with means for vertically reciprocating and giving said bucket a period of rest in its extreme upper position.

4. In a metal dipping machine, a dipper comprising a cylindrical bucket having a rod fastened thereto, an aperture in the side of said bucket, said dipper being constrained laterally by means of the inner bore of a tubular member having a plurality of circumferentially disposed slots and an aperture which periodically communicates with the aperture in said bucket and constantly with a delivery spout fastened externally to said tubular member, with means for vertically reciprocating said dipper and retaining its aperture, for a given period, in line with. said aperture in said tube.

5. In a metal dipping machine, the combination of means for successively securing a constant volume of molten metal, with means for elevating said metal, means for discharging same, and means for keeping said metal molten during said discharging period, substantially as shown and described.
